I learned that felines have (around) 6 times better night vision than us humans. It’s hard for me to get a reference as to how good that is. I thought a good starting place is: How many times better can humans see in the daytime vs the nighttime?
In: Biology
We have different cells in our eyes for day and night vision. The night vision cells are more sensitive but can only do black-and-white. That’s why you need a moment to adjust when the lights are turned off or back on – your eyes need some time to switch from one mode to another.
